Boring bars
BRASSINTER high density tungsten alloys provide rigidity and minimal vibration for Boring bars.
Using heavy tungsten alloys means improved machining finishes, increasing the tool’s working life and reducing costs.
Other advantages: Good corrosion resistance High thermal conductivity Easy to machine - Can replace tungsten carbide broaching bars. The tool can be broached on the tungsten heavy metal rod without altering the alloy’s physical properties.
Counterweights for aircraft and helicopter balancing
BRASSINTER tungsten alloys provide maximum weight in the smallest possible space. The components are manufactured according to the customer’s project.
The counter-weights are used in ailerons – aircraft flaps, helicopter rotors, high inertia rotating components, engine crankshaft trees, turbine shafts, rudder counter-weight stabilizers and in all mechanisms that need to rotate with perfect static and dynamic balance.
Other advantages: Good corrosion resistance High mechanical resistance Low thermal expansion
Defense
BRASSINTER heavy tungsten alloys can be used to manufacture molds and cases for bullets, missiles and fragmentation bombs.
They are also used in kinetic energy penetrators and as an option for depleted uranium.
Sporting goods
Darts Fishing and diving weights Golf club ballast
Mobile phone bobs
BRASSINTER high density tungsten alloys provide maximum weight in the smallest possible space and are not magnetic.
These counter-weights are placed on a motorized shaft unbalancing it and making the cell phone vibrate.
Other advantages: No magnetic field disturbance Good oxidation resistance
Vehicle components:
BRASSINTER high density tungsten alloys are used as counter-weights in crankshafts, pistons, ballast to change the center of gravity in race cars and other components.
Other advantages: Good corrosion resistance High mechanical resistance High thermal conductivity Low thermal expansion
Naval
Counter-weight and ballast for yachts, boats, sail boats and other vessels.
Radiation shields for industrial and clinical use
BRASSINTER tungsten alloys are completely lead free. When used as a shield against radiation for industrial and clinical purposes they offer a wide variety of advantages.
The physical size of components can be reduced without compromising the rigidity or efficiency of radioactive protection because Tungsten shield density is at least 50% greater than lead.
Other advantages: Good corrosion resistance More effective radiation protection Much better mechanical properties when compared to Lead. Damage resistant. Easy to machine.
Applications: Collimators X-ray and gamma radiation shield Nuclear shields Shields for syringes used in nuclear medicine Recipients for transporting radioactive nuclides. Recipients for radioactive isotopes.
HR Class tungsten heavy metal
This class of tungsten heavy metal has superior thermal and mechanical properties.
With the addition of molybdenum and strict atmospheric control during sintering, the finished product has high levels of hardness, traction resistance and thermal conductivity.
Other advantages: Erosion resistance Attenuates sticking / seizing Attenuates thermal fatigue Excellent heat exchange – accelerates cooling Easy to machine, weld and repair damage.
No thermal treatment required before or after machining.
Applications: Die casting tools Extrusion tools Electrode tip
WR Class tungsten heavy metal
